"The fastball guys say there's no data out there, and I guess you have to use some logic. What's the logic? If you smoke one cigarette, do you have the same chances of getting cancer if you smoke 20? I guess there's no study that specifically says that. But logically, we would say, 'Yeah, there probably is.'"

Let's break down Saban's logic:

Every play in a football game is dangerous

The more plays you run, the higher risk of injury you have

Therefore, the number of plays per game should be limited

The logical extension here is that there should be zero plays, because football is inherently dangerous.
